Question by: Keith S on May 17, 2025, 3:21 PM

got a 5.50 bore cylinder, is this seal the right size or am i gonna fight it

Answer by: Customer Support on May 19, 2025, 12:19 PM

It matches a 5.50 inch bore with a bore tolerance of ±0.002 inch. The groove diameter is 4.738 inches, and the seal cross section is 0.142 inch with a ±0.005 tolerance. It also lists a piston diameter F of 5.499 inch with a +0/-0.007 tolerance, which is the dimension given for pistons without wear rings.
